AB  - Taking into account the better agro-ecological adaptations developed over time to climate changed conditions, cereal local populations (landraces) represent a valuable plant genetic resources with their perspective reflected in the creation of better quality commercial cereal genotypes. The objectives of this research were to explore: i) the genetic variability of nutritional properties of Macedonian landraces of small grain cereals-wheat, barley, oat, and rye; ii) associations among nutritional properties; iii) strength and weakness of landraces based on nutritional properties profiles. Collecting missions were carried out in 2013 year in different locations of rural areas at the territory of Republic of Macedonia. Ten sub-samples of 100 g seeds were extracted from each of regenerated landrace in order to obtain a well-balanced analytical sample. All samples were analysed for moisture content - MOI (%), protein content - PC (%), fat content - FC (%), crude fibre content CF (%), wet gluten content - WG (%), and dry gluten content - DG (%). In regard to assessed nutritional properties the most perspective landraces proved to be: Okalesta bela (CF of (x) over bar = 2.62%) of bread wheat; Zimski (WG of (x) over bar= 9.24%), Dabilski nizok (DG of (x) over bar = 4.2%) and Ednoreden (CF of (x) over bar = 5.18%) of barley; Sopski (PC of (x) over bar= 14.62%), Gabarski (FC of (x) over bar = 6.46%) and Sekulicki (CF of (x) over bar = 9.89%) of oat; Calakliski (PC of (x) over bar = 14.43%, CF of (x) over bar = 8.16%), Koselski (FC of (x) over bar= 4.19%), and Gabarski (DG of (x) over bar = 3.14%) of rye. The positive associations among nutritional properties of Macedonian landraces of small grain cereals were: all examined nutritional properties except PC and CF in bread wheat landraces; PC, WG, DG, MOI as one cluster, and FC and CF as another cluster in barley landraces; all examined nutritional properties except MOI and CF in oat landraces; PC, CF, FC as one cluster and DG and MOI as another cluster in rye landraces. The Macedonian landraces of small grain cereals proved to be new sources of genetic variability of nutritional properties which can be used in breeding, because they outperformed commercial check cultivar landraces with statistical significance (P  lt  0.05) for: MOI (4 landraces) and CF (4 landraces) for bread wheat; WG (Zimski), DG (3 landraces), CF (7 landraces) for barley; CF (5 landraces) for oat; DG (1 landrace), MOI (4 landraces), FC (4 landraces in rye).

AB  - Intercropping, as a combination of different crops at the same time and the same field, enables interaction of their roots, improving plant growth and stress tolerance, thus improving nutritional quality of produced grains. The investigation was aimed to examine the effect of different cropping systems: intercropping in combination with alternating rows and alternating strips of maize and soybean, as well as single cropping, combined with different fertilization regimes (conventional, application of organic fertilizer, bio-fertilizer and control) on the antioxidant content (glutathione [GSH], phenolics and yellow pigment [YP]) in red maize and black soybean grain. Black soybean is richer in antioxidants than red maize. Season expressed the highest influence on the level of GSH, phenolics and YP in maize and soybean, while cropping system and fertilization regime influenced GSH and phenolics. The antioxidant level in grains with greater weight corresponded with an increased GSH level for maize, as well as an increased GSH and phenolic level for soybean, while smaller grains were characterised by the increased YP content. Generally, antioxidant content was increased mainly by alternating strips in maize grain and by alternating rows in soybean grain. Bio-fertilizer had the highest impact on an increase in GSH in maize grain and YP in soybean grain, while organic fertilizer was important for acquiring of GSH and phenolics in soybean grain.

Cilj istraživanja je bio da se ispita efekat različitih sistema gajenja: združeni usev kombinujući naizmenične redove i naizmenične trake kukuruza i soje, kao i pojedinačne useve, zajedno sa različitim režimima đubrenja (konvencionalni, upotreba organskog đubriva, bio-đubriva i kontrola) na sadržaj antioksidanta (glutationa [GSH], fenola i žutog pigmenta [YP]) u zrnu crvenog kukuruza i crne soje. Zrno crne soje je bogatije antioksidantima od crvenog kukuruza. Sezona je pokazala najveći uticaj na sadržaj GSH, fenola i YP kod kukuruza i soje, dok su sistem gajenja i đubrenje uticali na promene u sadržaju GSH i fenola. Sadržaj antioksidanata u zrnima sa većom masom je odgovarao povećanom nivou GSH kod kukurza, kao i povećanju nivoa GSH i fenola kod soje, dok su zrna manje mase imala već i sadržaj YP. Uopšteno, sadržaj antioksidanata je uglavnom bio povećan u zrnu kukuruza pri gajenju u naizmeničnim trakama, a u zrnu soje pri gajenju u naizmeničnim redovima. Bio-đubrivo je pokazalo najveći uticaj na povećanje sadržaja GSH u zrnu kukuruza i YP u zrnu soje, dok je organsko đubrivo ispoljilo uticaj na nakupljanje GSH i fenola u zrnu soje.

AB  - This research aimed to determine the effects of different cover crops and application of bio-fertilizer on dynamic of nitrogen in the soil and sweet maize yield. Also, we evaluated the effect of fall-winter species (common vetch, field pea, winter oats, fodder kale) and a mixture of vetch and field pea with oats used as cover crops, as such as dead organic mulch and traditional variant, without coverage on biomass, chlorophyll and protein content in leaves and grain of main crop. Biomass production and N uptake by cover crops ranged from 4.25 to 90.20 kg ha(-1) and from 0.34 to 133.80 kg ha(-1) N, respectively, depending on cover crop type. At harvest soil nitrate content in treatments with cover crops was 50-90% lower than in the control, reducing spring N leaching risk. Residual mineral N significantly increased with application of microbiological fertilizer. The chlorophyll content of the main crop was significantly lower in treatments without cover crops. Consequently, sweet maize yield was the highest in fodder kale and field pea (7263.83 and 7177.27 kg ha(-1)) treatments, but the smallest in winter oat and common vetch (6802.47 and 6184.14 kg ha(-1)). In terms of all investigated traits, particularly grain yield, cover crops and microbiological fertilizer expressed more efficiency in the dry year. It could be concluded that N content should be controlled effectively by sowing main crops after planting of cover crops in biological farming systems in a semiarid region.

AB  - This study concerned the effect of different intercropping systems (alternating rows and alternating strips) of maize and soybean compared with single cropping, in combination with different fertilisers (biofertiliser, organic fertiliser, and urea) on the potential availability of magnesium (Mg), iron (Fe) and zinc (Zn) from grain, through their ratio with phytate (as inhibitor) and beta-carotene (as promoter). The higher grain yield and land equivalent ratio obtained under alternating rows + biofertiliser treatment demonstrated the improved ability of crops in close proximity for better utilisation of existing agro-ecological conditions. Alternating rows + organic fertiliser decreased the molar ratios phytate : beta-carotene, phytate : Fe, phytate : Mg and phytate : Zn, indicating increased availability of the mineral elements in both crops. However, alternating strips + organic fertiliser contributed mostly to an increase in beta-carotene, Mg, Fe and Zn concentrations in soybean. Increased grain yield of both crops was followed by decrease in beta-carotene and increase in phytate, particularly in maize. In soybean, beta-carotene could be considered as the main contributor to Fe availability. Accordingly, cropping in alternating rows or strips, combined with biofertilisers, could serve as fortification measures for improved nutritional quality of maize and soybean grain, without grain yield losses.

AB  - The evaluation of pumpkin (Cucurbita maxima Duch.) and maize (Zea mays L.) intercropping productivity, under different farming systems: conventional farming vs. conservation farming was carried out on the chernozem type of soil at Zemun Polje, Serbia. Results obtained by the bivariate analysis of variance showed significant differences between different proportions of components in intercropped maize and pumpkins. Regarding the land equivalent ratio (LER), two rows of pumpkins and two rows of maize (proportion 2/3:1/3) were the optimum spatial arrangement in conventional farming system, while proportion 1/3:2/3 was optimal in conservation farming system. The yield of pumpkins proportionally increased with the increase of the plant population, although the intraspecies competition of pumpkins was very pronounced in intercropping with maize. The average fruit yield of pumpkins in the first year was lower in conservation farming practices in comparison with conventional farming practices. On the other hand, situation was complete opposite with pumpkin yield in second year of investigation, while significant decrease in maize yield was observed in the plots where conservation farming practices were applied. Growing pumpkins in mixture with maize probably costs a small farmer very little more effort, than the production of a sole stand of maize. At least where the productivity of mixture is dominated by one species, as with maize in maize-pumpkins intercropping, the competitive effect of the recessive species on the dominant is small.

Growing pumpkins in mixture with maize probably costs a small farmer very little more effort, than the production of a sole stand of maize. At least where the productivity of mixture is dominated by one species, as with maize in maize-pumpkins intercropping, the competitive effect of the recessive species on the dominant is small.",

AB  - World population is growing exponentially and agricultural production must meet the needs of the food. An attractive strategy for increasing productivity per unit area of land available is to intensify land use.

One of them is intercropping - growing two or more crops in the same space at the same time. This system leads to an increase in productivity per unit area of land through better use of resources, to reduce the risk, reduce competition from weeds and leads to the stabilization of yields.

AB  - Intercropping systems could improve utilization of the most important resources (soil, water and nutrients), provide a better control of weeds, pests and diseases, and finally higher productivity, especially under rain-fed growing conditions. This study aimed to determine the effects of three maize (Zea mays L.) prolific hybrids (FAO 500, 600 and 700) and the spatial intercrop patterns on the above-ground biomass and grain yields of maize and soybean (Glycine max L. Merrill), on chernozem soil type at Zemun Polje, Belgrade, in 2003, 2004 and 2005. The experimental design was a complete randomized block with four replications and three treatments: 3 rows of maize and 3 rows of soybean in strips for each maize hybrid (three variants, 3 rows of maize and 3 rows of soybean in alternate rows for each hybrid (another three variants) and monocrops of both maize and soybeans. To optimize the ecological and economic benefits of maize/soybean intercrop in terms of yield, variety selection and compatibility of the component crops should be made using established agronomic management practices involving the two crops. Suitable maize varieties for maize/soybean intercrop systems are varieties that have less dense canopy. These varieties would therefore have lesser shading effect to the understory beans. However, establishment of an appropriate spatial arrangement of the component crops would be essential to alleviate negative effects especially on the less competitive crop. The intercropping system in alternate rows showed significantly higher above-ground biomass and grain yields in comparation with both the strip intercropping system and maize monocrops in 2004. Soybean gave significantly lower above-ground biomass and grain yield in intercrops than in monocrops. Maize prolific hybrid growing in intercropping with soybean as legume crop, increased productivity of cropping system, especially in favourable agroecological conditions. Maize and soybean yields reduction could have also been due to inter-specific competition for resources such as nutrients and water. Moreover, performance of the currently grown varieties in the semi-arid regions depends on the amount of rainfall received during the growing season.

Cilj ovih istraživanja jeste da se utvrde uticaji tri različita višeklipa hibrida kukuruza (FAO 500, 600 i 700) i prostornog rasporeda (naizmenični redovi i trake) na prinose nadzemne biomase i zrna združenih i čistih useva kukuruza i soje. Istraživanja su obavljena na zemljištu tipa černozem u Zemun Polju, Beograd, tokom 2003, 2004 i 2005. godine. Ogledi su izvedeni po planu potpuno slučajnog blok sistema u četiri ponavljanja i tri tretmana: združeni usev kukuruza i soje u trakama za svaki hibrid kukuruza (tri varijante), združeni usev kukuruza i soje u naizmeničnim redovima za svaki hibrid (još tri varijante) i čisti usevi kukuruza i soje. U združenom usevu u naizmeničnim redovima su dobijeni značajno veći prinosi nadzemne biomase i zrna kukuruza. Ispitivani višeklipi hibridi kukuruza iz različitih FAO grupa zrenja, gajeni u združenom usevu sa sojom, imali su pozitivan uticaj na prinos, kako nadzemne biomase, tako i zrna, ali samo u 2004. godini koja je ocenjena kao najpovoljnija sa stanovišta meteoroloških uslova, posebno količine i rasporeda padavina.

AB  - A field experiment was conducted in order to estimate the influence of different arrangement patterns of maize plants (Zea mays L.) in combination with low rates of herbicides on weed infestation and on production parameters of the crop. The maize was sown at 70-, 50-, and 35-cm row space with the same crop density. The weed biomass declined with smaller row spaces and was, on average, the lowest with the 35-cm row space; even though the arrangement patterns of the maize plants had no significant effect on the average values of the weed biomass. The interaction of the arrangement pattern and the herbicide rate significantly influenced weed biomass. Maize grain yield expressed the greatest variation under the effects of applied factors, but did not differ significantly between treatments with the full and the half rate of herbicides. The results indicate that it is possible to control weed infestation level if maize is grown with increased spatial uniformity and combined application of other practices such are herbicides. In such a way, maize plants are more competitive against weeds and even lower amounts of herbicides could be applied in order to achieve high yields.

AB  - Weeds are among main limiting factors in sweet maize production. Commercially grown sweet corn hybrids (Zea mays saccharata Sturt.) vary widely in competitive ability against weeds which interference differentially affects yield and ear traits important to processing and fresh markets. A total of 28 sweet corn hybrids of different FAO maturity groups have been developed at the Maize Research Institute, Zemun Polje, and released by the the Commission for the Variety Releasing. In order to obtain high yields of good quality the scientists have been searching for the most appropriate growing practices. Therefore the objective of the present study was to determine the effect of four plant densities (40 000, 50 000, 60 000, and 70 000 plants/ha) on the level of weed infestation, yield and shelling percentage of four sweet maize hybrids (ZP 424su, ZP 462su, ZP 504su, and ZP 521su) in 2008 and 2009. Total fresh weight and the total number of weeds decreased with increasing sowing density, which was more prominent in 2008. Results of the analysis of variance showed that investigated factors, year, sowing density and hybrid had significant influence on fresh ear yield and shelling percentage. Sowing density affected fresh ear yield in the way that the denser sowing was, the higher yield was. Hybrids ZP 424su and ZP 462su gave higher fresh ear yields than other two. However, hybrids with less fresh ear yield (ZP 504su and ZP 521su) gave better shelling percentage. These results suggest that ZP 424su and ZP 462su can be preferable for fresh consumption and ZP 504su and ZP 521su for processing.

AB  - The level of weed infestation directly affects the intensity of competitive relationship between sunflower crops and weeds. The greatest damage is caused by annual, broad-leaf and invasive weeds, such as Ambrosia artemisiifolia L., Xanthium strumarium L. and Datura stramonium L. Suppression of these weeds is difficult because of deficiency of adequate herbicides and because in years with dry springs, such as in 2009, the use of herbicides gives no results. This two-year study dealt with the observed effects of pre-emergence flurochloridone + s-metolachlor herbicides on the distribution of weeds in different stages of sunflower development. Weed infestation was estimated over the sunflower developmental stages, i.e., in the periods when weeds were removed and when the total fresh and dry biomass of the weed species was determined. Simultaneously, in order to monitor the effects of weeds in dependence on herbicides application and the duration of competition, the sunflower plant height was measured. At the end of the life cycle, the yield and the oil content of the sunflower seeds were established. The total fresh weed biomass changed in dependence on the sunflower developmental stages and was always lower on the herbicide-treated area. This affected the sunflower plant height, yield and the oil content, which were higher, on the average, in the variants with herbicide applications (70.4 cm, 2959.7 kg ha-1 and 42.0%) than in the variants without herbicides application (57.4 cm, 2711.1 kg ha-1 and 40.1%). Weed suppression in the sunflower crop has to be done with adequate herbicides and in due time in order to suppress a significant reduction in morphological and yield parameters.

AB  - Intercropping two or more crops under similar micro environmental conditions can increase the agricultural productivity. A field study was conducted in three-year period 2003-2005 at experimental field of Maize Research Institute, Belgrade on chernozem soil type. This examination included three experimental hybrids of maize from various FAO groups of ripening (500,600 and 700) and the type of soya bean from II group of ripening (Nena). Maize and soybean was grown in pure stands and three combinations of intercrops (alternate-row and in strip intercropping). Additive design was used for creating of intercrop variants. The paper investigated the grain yield of maize and soya bean in the intercropping, and compared with the yield of the monocrops. Comparison of the yield was carried out with the most Number indicators- Land equivalent Ratio index (LER). For individual comparisons used the standard error differences between means. Comparing with the intercropping production of monocrops production of maize and soya bean, with the index LER, the results obtained indicate that there are more intercropping production, especially in 2004. The three-year average, the increase of grain yield in the intercropping in relation to monocrops of maize and soya bean was 45% in the strip, or 49% in the alternate rows. Intra-species the intensity of competition is higher in the strip and in the pattern arrangement of the resulting lower relative grain yield, primarily due to lower maize yield.

AB  - Growing competitive crops is an important component of the integrated weed management system, although selection of genotypes with the increased competitive ability is rather difficult. The possibility of reducing weed infestation by increasing the competitive activity of crops by growing genotypes, i.e. hybrids that better 'endure' a greater density, depends on the FAO maturity group and morphological properties of a genotype, environmental conditions and the growing regions. The competition between maize and weeds varies over the modified crop arrangement pattern. The greatest weed infestation is recorded in the crops of the sparse-spaced plants, while the height and the weight of weeds are significantly lower in closely-spaced plants. The height, growth intensity in the initial stages, embryo vigour and leaf area of the plant are important for a greater competitive ability, as they are components of competitive effects of crops on weeds. Weed infestation and maize hybrids yielding were studied in dependence on the hybrids arrangement pattern and the application of herbicides. Obtained results show statistically significant differences in the weed fresh weight, but only in certain years and in accordance with differences in the height and the leaf area of ZP maize hybrids.

Kompeticija između kukuruza i korova se menja sa promenom gustine i rasporeda gajenih biljaka. Najzakorovljeniji su usevi retkog sklopa, dok su visina i masa korova u usevima gustog sklopa znatno niže.

U radu je ispitivana zakorovljenost i produktivnost različitih hibrida kukuruza u zavisnosti od prostornog rasporeda u kome su gajeni i primene herbicida.

AB  - Successful double cropping of soybean is not possible without irrigation, especially under reduced tillage systems. Common application of conservation faming systems and doublecropped soybean production are limited mostly by expensive herbicide treatments. Adoption of advanced growing techniques through narrow sowing and decreased interrow distance are crucial to improve crop competitiveness against weeds. The level of weediness and yield of double cropped soybean have been examined on the experimental field of the Maize Research Institute at Zemun Polje. During the investigation, two different soil tillage systems: conventional and conservation; two interrow distances: 76 cm and 38 cm; and two herbicide treatments were evaluated. The average weediness of doublecropped soybean, expressed as fresh biomass of weeds, was lower under conventional soil tillage than conservation tillage, especially on the variants with narrow row distance and herbicide application. Lower weediness in these specific treatments resulted in a signficant grain yield increase of doublecropped soybean.

AB  - Decrease in the number and biomass of weeds, especially of perennial ones, is one of the advantages of intercropping. The results obtained in the first two years of investigation (2003 and 2004) show that the number of perennial weeds and their fresh weight were lower in both plant arrangement patterns in intercrops than in maize and soybean monocrops. However, in 2005, the arrangement pattern in strips was the only efficient pattern in terms of weed fresh weight per area unit. In the dry year of 2003, the plant arrangement pattern in alternate rows was advantageous, while the pattern in strips was more efficient in 2004 and 2005. Intercropping affected maize more favourably than soybean crops, in which the positive effect was most evident in 2005, especially in strips, and it mainly related to the number of weed plants per species. The longer the growing season of studied maize hybrids was, the less intensive was weed distribution in monocrops. Such a regularity was expressed in intercrops in 2003 in both plant arrangement patterns, while in 2004 and 2005 intercropping in strips was efficient with late maturity hybrids, especially in relation to weed fresh weight.
AB  - Jedna od prednosti združivanja useva jeste smanjenje broja i mase korova, naročito višegodišnjih. U prve dve godine ispitivanja (2003. i 2004), broj višegodišnjih korova i sveža masa korova bila je manja u oba prostorna rasporeda u združenim u odnosu na čiste useve kukuruza i soje. Međutim, u 2005. godini, samo je prostorni raspored u trakama ispoljio efikasnost u pogledu sveže mase korova po jedinici površine. U sušnoj, 2003. godini, prednost je bila na strani združivanja u naizmeničnim redovima, a u 2004. i 2005. godini, veću efikasnost je ispoljio drugi prostorni raspored - trake. Združivanje useva je povoljnije delovalo na kukuruz, dok je kod useva soje pozitivan efekat združivanja najuočljiviji u 2005. godini, posebno u trakama, a uglavnom se odnosi na broj jedinki korova. Zakorovljenost čistih useva kukuruza se smanjivala sa povećanjem dužine vegetacionog perioda ispitivanih hibrida kukuruza. U združenim usevima takva pravilnost je ispoljena u 2003. godini, u oba prostorna rasporeda, dok je u 2004. i 2005. godini, združivanje u trakama sa kasnostasnijim hibridima kukuruza ispoljilo efikasnost, posebno u pogledu sveže mase korova.

AB  - The effects of different herbicide combinations: control (1), alachlor+linuron (2), and alachlor+linuron+imazethapyr (3) were investigated in double-cropped soybean grown in two row spacing variants, 38 cm and 76 cm, under conventional tillage (CT) or no-tillage (NT). In trials conducted on a sandy loam soil at Zemun Polje, high weediness had a negative effect of on the yield of double-cropped soybean, especially at the higher row spacing tested and with no-tillage. Regression and correlation data revealed a dependence of weediness in double-cropped soybean on tillage system and herbicide combination, and dependence of soybean yield on tillage system.

AB  - Weeds have been a limiting factor in agriculture since the beginning of its development. With the intensive cultivation of certain corps, weeds, due to their great adaptability, have evolved to be more or less resistant to common systems of suppression. This weed resistance has lead to the increased use of herbicides, which furthermore has increased the total production costs and risks to the environment and human health. Therefore, other, alternative measures for weed suppression should be applied. Weed control measures are one of the natural ways of solving problems related to crop weediness, which can be achieved by special systems of cropping in which intercrops have an important role. The aim of this study was to determine the effects of different maize hybrids and spatial maize-soybean intercrop patterns on the floristic composition of the weed community in spring. The trial was carried out according to the additive intercropping system under rainfed conditions in the experimental filed of the Maize Research Institute, Zemun Polje on chernozem in 2003 and 2004. The weed community in the maize-soybean intercrop consisted of 15 weed species during the two-year studies. Solanum nigrum (L.) and Amaranthus retroflexus (L.) were dominant annual weed species, while Sorghum halepense (L.) Pers. prevailed among perennial weed species. The greatest, i.e. lowest number and weight of weed species were measured in monocrops, i.e. in maize-soybean intercrop sown in alternate rows (29.3 m-2), respectively.

AB  - Due to the absolute dominance of maize in a sowing structure of the arable areas, maize continuous cropping is still very frequent. It is followed by a two-crop rotation (winter wheat-maize), and then by a very favorable, ever more presented, three-crop rotation (winter wheat-maize-soybean). Nevertheless, maize continuous cropping is considered questionable due to an occurrence of a dangerous pest - western corn rootworm (Diabrotica virgifera virgifera La Conte), which is for now efficiently suppressed only by the crop rotation. This objective of this study was to observe effects of the two- and three-crop rotation on the grain yield in comparison with continuous cropping of winter wheat and maize during the period 2000-2004. Winter wheat and maize were grown on leached chernozem under rainfed conditions. The analysis of variance of the winter wheat and maize yield shows significant differences over years of investigation. The highest (4.30 t ha-1), i.e. lowest (3.70 t ha-1) yield of winter wheat in continuous cropping was obtained in 2001 and dry 2003, respectively. Winter wheat grain yield in the two-crop rotation (4.10 t ha-1) and the three- crop rotation (4.11 t ha-1) was statistically very significantly higher than the grain yield recorded in continuous cropping (3.70 t ha-1). Maize grain yield in continuous cropping (6.89 t ha-1) in the investigation period was statistically very significantly lower than the grain yield in the two-crop rotation (7.44 t ha-1) and the three-crop rotation (7.61 t ha-1).
AB  - Zbog apsolutne dominacije kukuruza na oraničnim površinama u setvenoj strukturi, monokultura kukuruza, je i dalje jako česta pojava. Na drugom mestu je dvopoljni plodored (ozima pšenica - kukuruz), a ono što je vrlo pozitivno je sve zastupljeniji tropoljni plodored, u čiji sastav ulazi i soja. Monokultura kukuruza je dobrim delom dovedena u pitanje, prvenstveno zbog pojave opasne štetočine - kukuruzove zlatice (Diabrotica virgifera virgifera La Conte) jer jedina prava i efikasna mera za suzbijanje ove vrste, za sada, je plodored. U ovom radu je ispitivan uticaj gajenja pšenice i kukuruza u dvopoljnom i tropoljnom plodoredu u odnosu na prinos ovih useva u monokulturi, u periodu od 2000 do 2005. Tip zemljišta na kome su gajeni ovi usevi, u uslovima prirodnog vodnog režima, je izluženi černozem. Na osnovu statističke analize dobijenih rezultata, došlo se do zaključka da su prinosi ozime pšenice i kukuruza u ispitivanim godinama bili statistički značajno različiti. Najviši prinos ozime pšenice u monokulturi dobijen je u 2001. godini (4,30 t/ha), a najniži u sušnoj 2003. godini (2,90 t/ha). Dobijeni prosečni prinosi zrna pšenice u dvopoljnom (4,15 t/ha) i tropoljnom plodoredu (4,19 t/ha) su se statistički vrlo značajno razlikovali od prinosa ostvarenog gajenjem ovog useva u monokulturi (3,77 t/ha). Prosečan prinos zrna kukuruza u monokulturi za period istraživanja (6,94 t/ha) je bio statistički vrlo značajno niži u odnosu na prinos dobijen u dvopoljnom (7,73 t/ha) i tropoljnom (8,11 t/ha).

U ovom radu je ispitivan uticaj gajenja pšenice i kukuruza u dvopoljnom i tropoljnom plodoredu u odnosu na prinos ovih useva u monokulturi, u periodu od 2000 do 2005. Tip zemljišta na kome su gajeni ovi usevi, u uslovima prirodnog vodnog režima, je izluženi černozem. Na osnovu statističke analize dobijenih rezultata, došlo se do zaključka da su prinosi ozime pšenice i kukuruza u ispitivanim godinama bili statistički značajno različiti. Najviši prinos ozime pšenice u monokulturi dobijen je u 2001. godini (4,30 t/ha), a najniži u sušnoj 2003. godini (2,90 t/ha). Dobijeni prosečni prinosi zrna pšenice u dvopoljnom (4,15 t/ha) i tropoljnom plodoredu (4,19 t/ha) su se statistički vrlo značajno razlikovali od prinosa ostvarenog gajenjem ovog useva u monokulturi (3,77 t/ha). Prosečan prinos zrna kukuruza u monokulturi za period istraživanja (6,94 t/ha) je bio statistički vrlo značajno niži u odnosu na prinos dobijen u dvopoljnom (7,73 t/ha) i tropoljnom (8,11 t/ha).",

AB  - In recent times little attention has been paid to the crop rotation, as a system of utilization of the arable land under different crops (mainly annual ones). Reasons for the introduction of the crop rotation are numerous, and they are classified into biological, agro technical and organizational-economical ones. According to various research works in the World there are evidences that a proper crop rotation can solve about 70% problems related to pests and diseases. This paper deals with effects of the three- and four-crop rotation on the grain yield compared with winter wheat continuous cropping. Grain yields were recorded in the regular crop rotation experiment set up in the experimental field "Radmilovac" of the Faculty of Agriculture, during the period of 2000-2004. In the three-crop rotation variant following crops were maize, soybean and winter wheat. The four-crop rotation encompassed maize, winter wheat, red clover and spring barley + red clover. The winter wheat cultivars Pobeda grown under rainfed conditions on leached chernozem was studied. The analysis of variance of the winter wheat yield showed significant differences among years of investigation. The highest yield of winter wheat (4.53 t ha"1) was obtained in 2001, while the lowest one (3.05 t ha"1) was recorded in dry 2003. Grain yield of winter wheat in continuous cropping (3.70 t ha"1) was statistically very significantly lower than grain yield in the three- (4.11 t ha"1) and four-crop rotation (4.07 t ha"1), while difference in grain yield between the three- and the four-crop rotation variants was no statistically significant.
AB  - Plodoredu kao sistemu korišćenja obradivih površina gajenjem različitih useva (uglavnom jednogodišnjih) se u poslednje vreme pridaje mali značaj. Razlozi za uvođenje plodoreda su brojni, a dele se na biološke, agrotehničke i organizaciono-ekonomske. Prema mnogim istraživanjima u svetu došlo se do zaključka da se pravilnim plodoredom može rešiti oko 70 % problema koji se odnose na bolesti i štetočine u ratarstvu. U ovom radu je ispitivan uticaj gajenja pšenice u tropoljnom i četvoropoljnom plodoredu na prinos u odnosu na gajenje pšenice u monokulturi. Prinosi su mereni u okviru redovnih plodorednih polja na oglednom školskom dobru Poljoprivrednog fakulteta (Radmilovcu) u 2000,2001,2002,2003. i 2004. godini. U tropoljnom plodoredu zastupljeni su kukuruz, soja i ozima pšenica, a u červoropoljnom plodoredu kukuruz, ozima pšenica, crvena detelina i jari ječam+crvena detelina. Tip zemljišta na kome je gajena sorta ozime pšenice Pobeda, u uslovima prirodnog vodnog režima je izluženi černozem.
